Summary

Package:system

Support for Direct-IP mode type cards only. (QMI Support may be possible in future)

To enable access via a PPP interface instead of a LTE Interface, change direct IP mode with /port firmware set ignore-directip-modem=yes command and a reboot. Note that using PPP emulation mode you will not get the same max speeds as using the native lte interface.

Passthrough

Starting from RouterOS v6.41 some LTE interfaces support LTE Passthrough feature where the IP configuration is applied directly to the client device. In this case modem firmware is responsible for the IP configuration and router is used only to configure modem settings - APN, Network Technologies and IP-Type. In this configuration the router will not get IP configuration from the modem.
The LTE Passthrough modem can pass both IPv4 and IPv6 addresses if that is supported by modem.
Some modems support multiple APN where you can pass the traffic from each APN to a specific router interface.

Passthrough will only work for one host. Router will automatically detect MAC address of the first received packet and use it for the Passthrough. If there are multiple hosts on the network it is possible to lock the Passthrough to a specific MAC.
Note, that it will not be possible to connect to the LTE router via public lte ip address or from the host which is used by the passthrough. It is suggested to create additional connection from the LTE router to the host for configuration purposes. For example vlan interface between the LTE router and host.

To enable the Passthrough a new entry is required or the default entry should be changed in the '/interface lte apn' menu
